Great news! Analog is joining the vast majority of science fiction magazines, and starting to look at electronic fiction submissions. According to the announcement over at SFScope:

Effective at 11AM Eastern Standard Time on Tuesday, February 22, Analog Science Fiction and Fact will begin accepting-and preferring-submissions in electronic form. Electronic submissions will be accepted through http://analog.magazinesubmissions.com, where full instructions can be found.

Don't worry — if you've already submitted a story on paper, you'll still hear back via snail mail. [SFScope]
